Please help with this crush problem that i have!?

I have a crush. I'm a weird kind of girl and told his friends then they told him, of course. After days, i thought he won't mind, but he told me hi at least 3 times! But, he was also hanging on with this girl.I told my friend to ask him if he have a crush on me. When my friend came back, she said that my crush have a crush on me. But,she also stated that the first time she asked him, he said no, but his friends tormented him by telling him that if he have no crush on me, i would have a crush on somebody else. That broke my heart, i told him that he's not my crush already,but i'm still feeling guilty. Then he told me in a message that he already have a girlfriend that he answered on the day i told him that i love somebody else already. I know his gf by looking at his comments, i chat the girl and she said that they already broke up. Then when i met him again after summer, he was not looking at me. I just ignored him, but one time, he called me, but i was too embarrassed to see him. Then there are rumors that he have a crush on the new most beautiful girl on school.Pls. help, what would i do?He seems like a playboy who wants all girls like him, 'cuz one time, a friend have a crush on him, and he's doing the same to her like the as he he did to me!
